Detailed Description

This class tests ECN marking The test is divided into 3 sub test cases.

1) CE threshold disabled This test enqueues 100 packets in the beginning of the test and dequeues 60 (some packets are dropped too) packets with the delay of 110ms. This test checks that ECT0 packets are marked and are marked appropriately and NotECT packets are dropped.

2) CE threshold enabled. This test enqueues 100 packets in the beginning of the test and dequeues 60 packets with delay of 1ms. This test checks that the ECT0 packets are marked appropriately at CE threshold.

3) CE threshold enabled with higher queue delay. This test is similar to the 2nd sub test cases just with higher queue delay and aims to test that the packets are not marked twice Any future classifier options (e.g. SetAssociativehash) should be disabled to prevent a hash collision on this test case.
